The Ambaji deposit must have been exploited for copper, lead and possibly silver, during the pre-Christian era Śuṅga Period and the post-Christian era Kṣatrapa Period. This is strongly indicated from the analysis of the Ambāji metallic samples, Kṣatrapa era lead coins from Nagara (20º 41 '15" N, 70º 38 '33" E) and silver coins from the Buddhist site at Devnimori (23º 41 'N, 73º26 'E) (vide fig. 17.3 a and Table 17.6). The trace element analysis data (Table 17.7) clearly relate the Nagara lead coin with the Zawar ore and the Devnimori silver coin with the Ambaji ore.
